Question

What is the total resistance of one thousand 10 kΩ resistors in parallel? (a) 10 Ω (b) 10 ΜΩ (c) 1Ω (d) 10 kΩ

Answer 1

(a) 10 ohm

Step-by-step explanation:

When the resistors are connected in parallel then its overall resistance is decreases even it is less than the smallest resistance which are connected in parallel.

For example if n resistors are connected in parallel each of value R then its equivalent resistance will be R/n

So here 1000 resistors are connected in parallel each of 10 k ohm so the equivalent resistance will be
`(10000)/(1000)=10\ ohm`

So the option (a) will be correct answer
